摘要： PURPOSE: To permit a cartridge having a diameter of a base portion of a vari able cartridge case, by mounting a frontward end which protrudes exceeding a lower surface of a breech block slide on a floating range ridge at a position in front of a range ridge. CONSTITUTION: When a breech block slide B retracts a spirally movable unit R located at a frontward position by firing or manually, a front face M1 of a hammer is supported by a rear end portion R5, and a nose R6 is protruded in a frontward direction from a breech insert C or a breech insert face C6. In this case, in a cartridge chamber J1 of a barrel J, when the nose R6 is protruded during retracting of the slide B, a ranging ridge R6 of the cartridge X of a selected diameter is disposed slightly above the upper surface of the nose R6 of a slide unit R, and a spring loaded nose E2 of a sleeve element E pushes a rear portion XX1 of the cartridge X and makes the cartridge X assuredly aligned with the cartridge chamber J1 of a barrel J. Furthermore, when the slide B is retracted by a distance enough not to move the breech insert C to the rear portion of the cartridge X, a nose of a kicker W flicks the cartridge case. In this manner, a high cartridge position can be obtained.

摘要： PURPOSE: To facilitate decomposition and assembly of a self loading firearm, by permitting release of a lock block by means of hold open means only at the time that a breech block slide is sufficiently held at a retracted position. CONSTITUTION: When a breech block slide B is held at the retracted position by means of a slide portion hold open engaging fitting E, a frontward and downward inclination angle G3 of an open engaging fitting G is removed from an end portion 13 of a locking engaging fitting and an arm E1 is removed from a frame recessed portion A5. A stud E15 is inserted on a locking block lug F14 and a lug 14 and an entire end portion of a locking block F are pushed down. Then, a barrel lug C8 is moved in a frontward direction on the rear portion of the locking block F, and the barrel C is removed from the slide B and the pistol. In this manner, when only the barrel is necessary, it can be easily removed from the firearm.
